Its been a while but I rolled out of bead at 4:00 am and gave these two a try. Venus was with the Thorlabs Venus filter and Saturn was captured through a Mead RGB filter set. 

Saturn is just a single 4.5 minute set since Winjupos seems to make the rings wierd for me.

That venus looks fantastic, what camera are you using with that Thorlabs filter?  I've got an older Astrodon-Schuler UVenus and wondering if it's your camera or the filter that really makes the clouds pop!?

I'm using the ASI290MM, so not the highest tech. I think the Thorlabs Filter is definitely the key, especially since it is a deep violet/near UV filter, so it does ok with the corrector and a barlow lense.

Very nice!  I really like the Thor 400/40 nm filter with my C11.  The Baader Venus filter was nearly unusable because of the long exposure times needed.

I'm gonna give Venus another try tomorrow morning. I own an ZWO ADC (never used it) and was wondering if the dispersion correction would be worth it with the extra UV absorbtion? The Thorlabs filter has a pretty narrow range, so would the dispersion be minimal?

Fine work indeed!
